Load Error, Cannot read file

• May 28, 2015 - 23:58

I was working on an arrangement in musescore with a double staff accordian part. I decided I didn't need the bass clef staff so I went to Edit > Intruments and deleted the accordian bass clef. Musescore then promptly crashed and I have been unable to open the file since, instead I get a load error: "Cannot read file". Does anyone know how I could fix this and get my arrangement back?

You can post the file and people can take a look. Also, after the crash, next time it started, it should have offered to recover the score. Did you say yes?

An MSCZ file is basically a ZIP archive, and should be openable in any ZIP program. This one cannot. but probably there exist utilities that can try to repair corrupt ZIP files - you might try hunting one down. Meanwhile, though, you should probably also look for the backup files as suggested elsewhere.

OK... so, for Windows7 you have two places to look for a backup file:
1. The 'mscz,' file (with the comma) - this should be located in the same folder you keep your scores.
Once you locate this file, rename it and remove the dot and the comma (and on Windows also unset any hidden attribute). You should be able to open the resulting file in MuseScore.

2. The session file - for Windows7 location is:
C:\Users\ your user name\AppData\Local\MuseScore\MuseScore2\

Session files have alphanumeric names which do not resemble the file's user assigned name. Here's an example: scPa5800.mscz
You will have to open a session file in MuseScore to see if it's the one you're looking for.

If any file extensions or folders are hidden so you can't see them:

Unfortunately, same story here - this file seems to contain no useful information. You'll need to try the same recovery methods spelled out in the other responses. What version of MuseScore were you using when this happened? Anything unusual that happened (eg, a system crash or power outage) leading up to this?

This is my sheet music. I have the same problem.
Every time I add in a song to the medley, it won't open the next day, but I sense a pattern.

The file on download is 59.2 KB, while when I add a few songs in, it becomes 66.0 KB. It crashed.
Today, I added songs to make it 60.4 KB. It crashed too.

Maybe it has to do with the size of the sheet music.

My file wont open either. I dont know what to do. its due tomorrow. im using windows 10 on the newest version of musescore. Im so frustrated as i spent hours working on my first composition project, and now i cant open it.

I had the same problem. My computer died while I was working on the score. Problem is, I spent about 4 hours on it and didn't save. When asked to recover it, I hit yes but it wouldn't read the file. I went and found this in the autosave backups but it still won't read. Any way I can get it back?

That file looks to be broken beyond repair. But assuming you weren't literally in the middle of a save operation when the computer died, just open the actual file. It won't have your work since the last save of course, but it should be fine. Also, the backup file in the same folder as the actual file (name starting with period and ending with comma) should be fine.

Just_Chillen'.mscz is 0 bytes, so doesn't really exist, resp. is entirely empty, nithing anyone can do anything about (except for you searching a backup).
Eureka Octet.mscz ends prematurely at measure 103. Might be possible to fix is so it at least loads up to that point.
I attached the 'debris', the extracted truncated mscx. Needs some further editing to make it a score that MuseScore can open...

I've looked at that several different times and it doesn't make sense to me.

"Backup files are hidden, by default, on Linux and Mac OS X systems because the file name starts with a dot; and on Windows because MuseScore sets the "Hidden" file attribute. To make these hidden files visible, refer to the relevant OS documentation".

What is the relevant OS documentation? How do you find these hidden files?

There isn't even a zip file-header: A file with only zeros ...
I wonder how this happened twice.
Can you help to solve this unsolved problem?

Do you have a guess about this subject?
For example, was it the last thing you noticed?
Do you often save manually?
Is the Musescore open all the time?
Or do you quit and relaunch it from time to time?

Unfortunately it seems to have been corrupted somehow. please see the article linked in other responses to this thread to learn how to find a backup copy. Also, if you are on Widnwos and didn't disable OneDrive when setting up your computer, a nice safe backup copy of it and all your other files is sitting on the OneDrive site waiting for you to restore it.
